After secondary osteoplasty radiographic assessment was carried out on 101 patients with cleft lip, jaw and palate (CLP) with 129 uni- and bilateral clefts. The bone formation in the grafted area was assessed on dental radiographs taken 2.9 years on average after secondary osteoplasty. Patients were assigned to 4 groups (Types I to IV) with Types I and II being rated as a success. The purpose of the study was to compare the results in terms of the patients' age at time of surgery, presence or absence of the lateral incisors and prosthetic or orthodontic space closure. The best results in grafted bone height were observed among 6- to 9-year-olds and when the space in the dental arch had been closed orthodontically. If even hypoplastic lateral incisors were preserved, growth into the grafted area could be observed, resulting in successful bone formation of Types I and II. Space due to missing lateral incisors could best be orthodontically closed in the youngest age group and resulted in favorable septal height. The results obtained for the over 14-year-olds were least satisfactory. A reduced septal height was observed and space closure had to be obtained most frequently by prosthetic means.
对101例唇腭裂（CLP）患者的129处单侧和双侧腭裂进行二期骨成形术后，进行了影像学评估。在二期骨成形术后平均2.9年拍摄的牙科X光片上，评估移植区域的骨形成情况。患者被分为4组（I型至IV型），I型和II型被评定为成功。本研究的目的是比较手术时患者年龄、侧切牙的有无以及修复或正畸关闭间隙方面的结果。在6至9岁的患者中，以及当牙弓间隙通过正畸方法关闭时，观察到移植骨高度的最佳结果。如果保留了发育不全的侧切牙，可观察到其向移植区域生长，并成功形成I型和II型骨。由于侧切牙缺失导致的间隙，在最年轻的年龄组中最适合通过正畸方法关闭，从而获得良好的鼻中隔高度。14岁以上患者的结果最不理想。观察到鼻中隔高度降低，且最常通过修复手段来关闭间隙。
